IMPROVEMENT IN LAMPS.

The Schedul referred to in these Letters Patent and making part0! the same.

ment in Lamps forburuing kerosene or .oil rich in carbon; and do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawing, of which- Figures 1 and 2 are vertical sections of one of my improved lamps, the planes of the sections being .at right angles to each other.

The lamp as improved by mejs analogous to that described in Letters Patent No. 29,203, dated July 17, 1860, and granted to Isaiah W. Taber, inasmuch as it has two separate wick-tubes or holders, and a central draught or air-duct arranged directlybetween them.

I dispense, however, with the lateral inducts as used by the said Taber to convey air to the central duct, and, instead of such, I employ with such central ,duct :1. tube, to be arranged in the lamp-reservoir, and open through the bottom or outside thereof, and to extend up therefrom to or into such central duct.

Furthermore, I combine with the central duct and the wick-holders a trumpet onguide-mouth, arranged therewith substantially as represented in the drawing, the object of it being to guide the wick-carrier tube or tubes upon the auxiliary air-tube 01' duct, and the latter into the air-duct orspace between the two wickcarriers.

In the drawing- A A denote the two wick-carriers or tubes, formed within a longer tube, B, and having between them an 'air-duct, open space, or passage, C.

At its lower end the tube B is open and provided with a llariug guide or mouth-piece, D, and wings, E E, arranged therewith as represented, so as .to form passages, P 1, for reception of the two wicks.

The two wicks are to be run-between the said mouth-piece and the wings, and thence are to pass up into thetube B, and thence up through the two holders A A.

The air-supply duct or tube is shown at F as extended up from the bottom of'the oil-reservoir G, and

through the guide-mouth, and into the passage be-- tween the two wicks or their holders.

1 The reservoir being provided with feet H to support it, air will pass from beneath it up through the duct F to the wick or the space between them.

.The air for supplying the outersurtaces of the flames-of the wicks rushes through the foraminous base I, and thence into and. through .the cone-deflector usually placed on such base, and employed with the two wick-tubes A A and control-draught G, as described.

The burner may be held to the oil-reservoir by a.

bayonet catch ring, or an annular collar arranged to revolve on t he"burner, and to screw upon or into the neck of the reservoir. 1

I claim- 1. The arrangement and combination of the guide A or flaring mouth-piece l) with the tube B, the wickholders, the central passage, and the tube I the whole being applied to the burner and the lamp-reservoir, substantially in manner as explained.

2. The combination of the wick-passages P P, on opposite sides of the flaring mouth-piece,-with such mouth-piece, the tube B, the two wick-holders A A,

and their passage 0, arranged betweenthem, all as set forth.
